Raynaud syndrome, also known as Raynaud's phenomenon, is a medical condition in which the spasm of small arteries causes episodes of reduced blood flow to end arterioles. [1] Typically the fingers, and, less commonly, the toes, are involved. [ 1 ]
In people with Raynaud’s phenomenon, cold temperatures or stress trigger spasms in the small blood vessels near the surface of the skin, causing the vessels to constrict and limit blood flow.
Raynaud’s disease is a rare peripheral vascular syndrome that narrows blood vessels, generally in the hands and feet, due to cold or stressful emotion. [8] It is recognized by the reduction of blood flow to fingers and toes with periodic spasm and results in a drastic color change to white or blue.
Buerger's disease – inflammation and swelling in small blood vessels, causing the vessels to narrow or become blocked by blood clots. [18] Raynaud syndrome – a peripheral vascular disorder that causes constriction of the peripheral blood vessels in the fingers and toes when a person is cold or experiencing stress. [19]
Vascular-related cutaneous conditions result from dysfunction of the blood and/or blood vessels in the dermis, ... Majocchi-Schamberg disease; ... Primary Raynaud's ...
HAVS is a widespread recognized industrial disease affecting tens of thousands of workers. It is a disorder that affects the blood vessels, nerves, muscles, and joints of the hand, wrist, and arm. Its best known effect is vibration-induced white finger (VWF), a term introduced by the Industrial Injury Advisory Council in 1970.
Patients with Raynaud's syndrome experience cut off blood flow from the fingers causing a large decrease in oxygen, which leads to the discoloration of the fingers. Using alpha blockers aids in restoring blood flow and treating the syndrome by stimulating the dilation of blood vessels.
Moreover, impaired blood flow resulting from abnormal vasoconstriction may contribute to tissue ischemia, which can be observed in conditions like Raynaud's disease. Understanding the pathology of vasoconstriction is crucial for developing targeted therapeutic strategies to manage conditions associated with abnormal vascular tone.
